SYNOPSIS

DESCRIPTION

Amfetchdump pulls one or more matching dumps from tape or from the
holding disk, handling the reassembly of multi-tape split dump files as
well as any tape autochanger operations.
It will automatically use the Amanda catalog to locate available dumps
on tape, in the same way that the find feature of amadmin(8) lists
available dumps.
The hostname, diskname, datestamp, and level dump specifications are
further described in amanda-match(7). Note that at minimum a hostname
must be specified.
Unless -p is used, backup images are extracted to files in the current
directory named:
If a changer error occurs, or the -d option is given, then amfetchdump
prompts for each required volume.
hostname.diskname.datestamp.dumplevel

OPTIONS

-p
Pipe exactly one complete dump file to stdout, instead of writing
the file to disk. This will restore only the first matching
dumpfile (where "first" is determined by the dump log search
facility).
-h
Output the amanda header as a 32K block to same output as the
image.
--header-fdfd
Output the amanda header to the numbered file descriptor.
--header-filefilename
Output the amanda header to the filename.
-ddevice_or_changer
Restore from this device or changer instead of the default,
prompting for each volume.
-Odirectory
Output restored files to this directory, instead of to the current
working directory.
-c
Compress output, fastest method available.
-C
Compress output, smallest file size method available.
-l
Leave dumps in the compressed/uncompressed state in which they were
found on tape. By default, amfetchdump will automatically
uncompress when restoring.
-a
Assume that all tapes are already available, via tape changer or
otherwise, instead of prompting the operator to ensure that all
tapes are loaded.
-n
Do not reassemble split dump files at all, just restore each piece
as an individual file.
-oconfigoption
See the "CONFIGURATIONOVERRIDE" section in amanda(8).

EXAMPLES

All the examples here assume your configuration is called SetA.
Here's a simple case, restoring all known dumps of the host vanya to
the current working directory.
$ amfetchdump SetA vanya
A more likely scenario involves restoring a particular dump from a
particular date. We'll pipe this one to GNU-tar as well, to
automatically extract the dump.
$ amfetchdump -p SetA vanya /home 20051020 | gtar -xvpf -

CAVEATS

Amfetchdump is dependent on accessing your server's config, tape
changer, and (normally) dump logs. As such, it's not necessarily the
most useful tool when those have all been wiped out and you desperately
need to pull things from your tape. Pains have been taken to make it as
capable as possible, but for seriously minimialist restores, look to
amrestore(8) or dd(8) instead.
